Highlights of High Level Assembler
High Level Assembler is a functional replacement for Assembler H Version 2 and DOS/VSE Assembler. It offers all the proven facilities provided by these earlier assemblers, and many new facilities designed to improve programmer productivity and simplify assembler language program development and maintenance.
Some of the highlights of High Level Assembler are:
- Extensions to the basic assembler language
- Extensions to the macro and conditional assembly language, including external function calls and built-in functions
- Enhancements to the assembly listing, including a new macro and copy code member cross-reference section, and a new section that lists all the unreferenced symbols defined in CSECTs.
- New assembler options
- A new associated data file, the ADATA file, containing both language-dependent and language-independent records that can be used by debugging and other tools
- A DOS operation code table to assist in migration from DOS/VSE Assembler
- The use of 31-bit addressing for most working storage requirements
- A generalized object format data set
- Internal performance enhancements and diagnostic capabilities
